Hop flour treatment

[Finman]

That is correct. It is:

"purified semi-solid extract from Humulus lupulus L. containing approximately 48% of beta acids as potassium salts"​

and they claimed that the "beta acids" were responsible for killing the mites, the same as is claimed for the flour.

Oh dear

I'm not waiting for evolution.
I'm selectively breeding for varroa tolerance (among other traits).

Ah! your avatar should have given that away....

If you had dusted them with anything icing sugar or bog standard flower you would likely find an increased drop.

Not quite the same though -https://healthyfocus.org/benefits-of-hops/

Not quite the same but very true and is the link to the info the same research the proposed manufacturer backed away from?

I've got a few botttles of distilled dragon tears surplus to my requirements this year - deadly against Varroa, Verrucca and great for getting stubborn stains out of underwear. PM me if anyone is interested, I will do a good deal for bulk purchase.

That's just put chilled water all over the works keyboard.......
